P a g e | 232 Internet Security and Privacy

With increase in usage of the Internet, there has been an exponential increase in the use of online social media on the Internet. Websites like Facebook, YouTube, Orkut, Twitter and Flickr have changed the way Internet is being used. There is a dire need to investigate study and characterize privacy and security of online social media from various perspectives (computational, cultural, and psychological). Real world scalable systems need to be built to detect and defend security and privacy issues on online social media. The main goals of the talk are to highlight and discuss latest issues, trends, and cutting-edge research approaches in security and privacy in online social media. Some of the prominent problems on which our group is working on are spam and phishing detection, credibility assessment, privacy leakage and fake profiles identification on online social media. The internet structure itself allowed many security threats to occur. The architecture of the internet, when modified can reduce the possible attacks that can be sent across the network. Knowing the attack methods, allows the appropriate security to emerge. Many businesses secure themselves from the internet by means of firewalls and encryption mechanisms. The businesses create an “intranet ” to remain connected to the internet but secured from possible threats. The entire field of network security is vast and in an evolutionary stage. The range of study encompasses a brief history dating back to internet’s beginnings and the current development in network security. In order to understand the research being performed today, background knowledge of the internet, its vulnerabilities, attack methods through the internet, and security technology is important and therefore they are reviewed
